I couldn't get to register on Plenty of Fish.
I know it's not allowed for some countries , I used HideMyAss VPN with a U.S IP , but I couldn't get to register .. I was keep getting an error saying something like "only text and characters allowed" or something like that even though everything was correct !

When I tried without the VPN (with my original IP from my country india) , it surely DID NOT work , because I was getting the message that i'm not allowed to register from my country , but when I tried with the VPN , I was getting that error ..

If you are looking to advertise then use this link to register https://ads.pof.com/
here they allow people from all countries to join but only people from some countries are allowed to be member of the dating site.

How can I join POF ,I would really appreciate if you could help me.

Are you trying to join POF or POF ads? Hidemyass is a well known and used proxy service, it wouldn't surprise me if the ip was banned. Another thing is since hma s a web based proxy, something might not be processing right with the scripts on hms and POF. Like stated above, contact Ben and he should be able to help you out.
